Leal Campos Fonseca da Silva, Renan (author)Spurs-and-grooves (SAG) are a common and impressive characteristic of shallow fore reef areas worldwide. Although the existence and geometrical properties of SAG are well-documented ever since the 50’s, the literature concerning specifically the hydrodynamics around them is sparse. This study provides a characterization of the 3D flow patterns...master thesis 2017

ZHANG, XINYI (author)Infragravity (IG) waves (0.005-0.04 Hz) are surface waves that can dominate the nearshore hydrodynamics and can impact various coastal processes (e.g., run-up, overwash). A proper offshore description of incident IG waves is required for storm impact models, which generally assume a local equilibrium between sea-swell (SS) waves (0.04-0.33 Hz)...master thesis 2022

Hoogendoorn, Hugo (author)Sandy beaches can be found all over the world and are on the interface between the sea and the land. Important functions of beaches are the protection of the inland to the forces of the sea and providing local opportunities in recreation. The impact of storm events on the beach is therefore an important topic of research especially with future...master thesis 2021

Hewageegana, Hithaishi (author)Coastal defense mechanisms are an integral part in the safety of infrastructure and communities residing on coastlines around the globe. In long temporal and spatial scales, traditional “hard structures” for coastal defense can become infeasible. Incorporation of soft engineering methods for coastal defense can then be a viable solution....master thesis 2017

Serrano Urena, A.M. (author)Posidonia oceanica is a flexible subaquatic seagrass species that forms extensive meadows across the Mediterranean Sea. These are considered one of the most valuable ecosystems on Earth. This MSc. thesis examines the role of P. oceanica in protecting the coast from storm impacts. Prior studies are based on flume experiments that focused, almost...master thesis 2016

Van Steijn, P.W. (author)Recently an innovative nourishment method has been applied as a counter measure for coastal recession in the Netherlands. This soft engineering solution, also known as the Sand Engine, consists of a shoreline perturbation of $21.5$ Mm\textsuperscript{3} sand which will be redistributed along the shore by the natural forces of waves, tides and...master thesis 2015

van den Ende, I.C. (author)This study investigates wave driven onshore sandbar migration. Observations show that sandbars move onshore during mild wave conditions. Literature describes different potential sediment mechanisms that cause this onshore migration, but the dominant cause is still under debate. The goal of the present study is to determine the dominant sediment...master thesis 2017

Bertoncelj, Vesna (author)Many coral reef islands are low-lying, which in combination with population growth, sea level rise and possibly more frequent extreme weather events is likely to result in increased coastal risk (e.g. Storlazzi et al., 2015). On smaller scales of O(10 km) wave-driven coastal inundation can be accurately predicted with advanced models such as...master thesis 2021

van de Ven, Maartje (author)This study investigates nonlinear wave shape and the near-bed velocity influenced in the vicinity of a tidal inlet for the SEdiment supply At the WAdden Sea ebb-tidal Delta project. Wave nonlinearities occur when waves encounter a flow. An opposing flow leads to waves with higher peaks and reduced wave length. During a following flow, the waves...master thesis 2018

Koudstaal, K. R. (author)The maximum wave run-up on a beach is an important factor in the design of coastal protection measures. Therefore, it is desired to predict this run-up based on numerical models. In this thesis, this is done with the use of the model XBeach. Wave run-up consists of multiple components: a swash height, S, and a wave set-up, <η>. The swash height...master thesis 2016

Fa, Chen (author)Recent analysis on measurements in the North Sea has shown a large amount of wave energy ranging in infragravity bands in the North Sea during storm events. To better understand the generation and propagation of free infragravity waves, the SWAN model is used to inspect the infragravity wave pattern, the infragravity wave origins, and the...master thesis 2021

Klaver, Sebastiaan (author)Many small island developing states (SIDS) are among the most vulnerable to climate change (e.g. sea level rise) and seasonal to inter-annual climate variability, and subsequently experience flooding due to swell waves and wind waves, coastal erosion and salinisation of freshwater lenses. To counteract this, reef flat mining for sand and...master thesis 2018

Van Engelen, T.E. (author)Coastal inundation models are benefited by timeliness of the predictions, not only when it comes to real-time forecasting but also considering risk assessment studies and sensitivity analysis. Numerical models however are often subjected to a trade-off between accuracy and efficiency, especially when dealing with large geographic scales. In this...master thesis 2016

Pearson, S.G. (author)Low-lying tropical islands are highly vulnerable to the effects of sea-level rise and climate change. Most pressing is the threat posed to their fresh water supplies by wave-induced flooding. This thesis attempts to generalize previous site-specific studies of flooding on coral atolls and apply it in a framework that can be used for early...master thesis 2016

van Noort, Rieneke (author)Coral reefs are vital to the prosperity of the world and the local communities by providing food and coastal protection. Coral reefs are home to 25% of marine life and have therefore gained the nickname ’rainforest of the sea’. However, the reefs are being damaged by climate change and human intervention, resulting in an alarming rate of...master thesis 2021

Jager, T. (author)This thesis investigates the governing generating mechanisms, shoaling and reflection behaviour of infra-gravity waves on a mild-sloping, macro-tidal, rocky shore platform. The methods comprise among others, field data analysis of the Lilstock platform, numerical modelling using a calibrated XBeach model and a cross-correlation analysis to...master thesis 2016

Roelvink, Floortje (author)Coral reefs are degrading at an alarming rate, affecting not only the precarious coral ecosystem but also human habitat. The combination of coral degradation, sea level rise and its exacerbated effect in the tropics, and the possible storm intensification increases the flood vulnerability of low-lying tropical islands. To protect reef fronted...master thesis 2019

Gensen, M.R.A. (author)Wave overtopping in harbour areas is a fairly untreated topic in the context of flood risk analyses. Pragmatic approaches were undertaken to evaluate the possible influence of wave overtopping on the frequency of flooding. However no consensus was reached on how wave overtopping in a harbour area could be quantified. Therefore it is also...master thesis 2017

Speth, Florine (author)Coral reefs are considered to be a crucial ecosystem and form of natural coastal protection. They owe their effectiveness to their high structural complexity. This complexity, which positively influences aspects like species richness, coral recovery, live coral cover, and coastal protection, is often quantified using parameters such as porosity...master thesis 2023

van Wiechen, P.P.J. (author)Atolls and coral islands in and around the Pacific and Atlantic Ocean largely rely on coral reefs for their coastal protection. On these reefs a large roughness is created by different coral species. The dissipative character of these species reduces the incident wave height, thereby reducing the amount of run-up on the coast. In our current...master thesis 2020
